A pressing apparatus for producing a food service paperboard container from a paperboard blank so that the paperboard container possesses an overturned rim provided with folds includes a first die and a second die that are movable relative to one another. The first die includes a first base and a first platform that is movable with respect to the first base, with the first base having a curved surface for engaging the outer periphery of the paperboard blank. The second die is positioned in opposing relation to the first die and includes a second base and a second platform that is movable with respect to the second base. The second die is movable with respect to the first die and the second base has a curved surface for engaging the outer periphery of the paperboard blank so that the outer periphery of the paperboard blank is pressed between the curved surface of the first base and the curved surface of the second base. A first cast-in heater is mounted within a recess in the first die and includes a resistor wire embedded within a thermally conductive cast-in material. A second cast-in heater is mounted within a recess in the second die and includes a resistor wire embedded within a thermally conductive cast-in material.

Food serving paperboard container pressing apparatus employing cast-in electrical heaters

A lid for use on a cup having a radially outwardly projecting non-helical brim extending around a mouth thereof. The lid is formed of plastic and comprises a center portion, and a flexible skirt extending downwardly from an outer periphery of the center portion. The skirt includes a radially inwardly projecting annular restriction ring adapted to be positioned beneath the cup brim. The skirt includes a plurality of threads spaced apart circumferentially around the skirt. Each thread extends generally helically upwardly from a location disposed between the restriction ring and a bottom edge of the skirt. The threads intersect the restriction ring to form circumferentially spaced caesurae in the restriction ring.

Lid for cups with non-helical brim

The drinking cup lid includes a cover portion and at least one tab extending from the cover portion and movable into a retaining position adjacent the sidewalls of the cup to securely attach the lid to the cup while providing a gripping area insulated from the thermal effects of the contents of the cup. The tabs include a retaining groove adapted to receive the rim of the cup and a latching lip for sealingly engaging the rim when the tabs are moved into the retaining position. A gripping portion of each tab is positioned adjacent the sidewalls when the tabs are in the retaining position. The gripping portion is maintained a spaced radial distance from the sidewalls by both a hinge which provides a pivot axis about which the tab rotates and a rib formed by a stiffening groove extending along the tab.
